Most indoor gardeners prefer to use carbon filters in their grow cabinets, even if they are not strictly necessary. Carbon filters are the best way to make sure your plants use the freshest air to grow, and they help eliminate odors and maintain a certain balance in different environments. Activated carbon filters are widely used to reduce odors and control emissions from cabinets and grow rooms. Carbon filters are essentially containers filled with activated carbon, which has many small pores that trap aromatic particles when air passes through them.
Usually, carbon filters are cylindrical because they provide the largest surface area and are added to the tent ventilation system. Activated carbon has nooks and crannies through which odorous compounds pass through the ducts and the filter. Using a carbon filter in your hydroponic ventilation system will allow you to work in and around your growing space. By using valence electrons, the activated carbon filter medium blocks odors and vapors at the molecular level.
If your goal is to eliminate odors that emanate from inside the tent, you will need to organize the ventilation system so that it draws air from the tent and passes it through the carbon filter before it leaves the ventilation system. The carbon filter, which is usually connected to the built-in fan or to the rear end of the duct, cleans the air that circulates through it. Carbon filters don't necessarily eliminate bad odors, but they prevent odors from spreading from the growing space. Investing in a carbon filter is worth it if you frequently drive in places with slow traffic or encounter strong odors when driving. Carbon has been used to filter air since World War I, when gas masks were used to destroy some lethal chemicals used against the military. Carbon filters don't require any additional equipment to set them up, just connect them to the ventilation system and turn on the fan.
They are an effective way of ensuring that your plants get fresh air and that any odors emanating from your grow cabinet are kept under control.
